The body shop did amazing work straightening the frame of my numbers-matching Corvette, but the auction house laughed when I tried to consign it. “Frame damage history,” they said, cutting my reserve price by 35%. I went back to my insurer for the $40,000 difference in value, and they pointed to the “diminished value exclusion” hidden on page 34.
Key Takeaways
- DV is Real for Classics: History is value. A wrecked-and-fixed classic is worth significantly less than a pristine one.
- First-Party DV Exclusion: Most policies explicitly state they will not pay for Diminished Value on your own car. They only pay to fix it.
- Third-Party DV: If someone else hits you, you can claim DV against their insurance.
- The “Total Loss” Pivot: Sometimes it is better to fight for a Total Loss payout than to accept a repair that leaves you with a devalued asset.
The “Why” (The Trap): The Payment of Loss Clause
The policy says: “We will pay the cost to repair or replace.”
It does not say: “We will pay to restore the value.”
Insurers argue that if the metal is straight and the paint is shiny, you have been made whole. They ignore the “Carfax Stigma” or the loss of “Survivor” status.

The Investigation: I Called Them
Who protects the value, not just the metal?
1. Porsche Auto Insurance (Brand Specific)
- The Feature: Agreed Value coverage.
- The DV Stance: They are one of the few that recognize value loss. If the repair prevents the car from being “Porsche Approved,” they may total it out and pay the full value.
- Verdict: excellent for specific marques.
2. State Farm / Allstate
- The DV Stance: “We do not cover Diminished Value on first-party claims.” Hard stop.
- The Advice: They told me to sue the other driver if it wasn’t my fault.
- Verdict: Useless for DV.
3. Appraisal Clause Strategy
- The Hack: If the insurer refuses DV, invoke the “Appraisal Clause.” Hire an appraiser to prove the “loss” includes the loss of value. It’s a legal fight, but winnable in some states (like Georgia).
Comparison Table
| Scenario | First-Party Claim (You hit a tree) | Third-Party Claim (They hit you) |
| Repair Cost | Covered | Covered |
| Diminished Value | Usually Excluded | Claimable |
| Difficulty | Extreme | Moderate |
Step-by-Step Action Plan
- Check Fault: If it wasn’t your fault, file the DV claim against the other driver’s insurance immediately. Do not claim it on your own policy.
- Get a Post-Repair Appraisal: Hire a USPAP appraiser to value the car “Pre-Accident” and “Post-Repair.” You need this paper trail.
- Push for Total Loss: If the DV is massive, argue that the cost of repair + DV exceeds the value. Ask them to pay the Agreed Value and take the car.
- Buy Back the Salvage: If they total it, buy it back. You get the cash, keep the car, and can fix it yourself (accepting the salvage title).
FAQ Section
Does a salvage title hurt value?
Yes, typically by 30-50%. This is why avoiding a total loss on a modern car is good, but on a classic, getting the Total Loss payout is often better than a bad repair.
Can I claim DV on a collision claim?
In Georgia, yes (state law). In most other states, no. You need to check your specific state laws regarding “1st Party Diminished Value.”
What if the parts aren’t matching anymore?
If the engine block is cracked and replaced, the car is no longer “numbers matching.” This is a massive value loss. Ensure your policy covers “Loss of value due to non-original parts.”
